Anit-Spyware program that can be run from Flash Drive or CD

I want to know if anyone is aware of any free or inexpensive Anti-Spyware programs that I can download onto a Flash drive and then run the scan and clean up directly from there without doing an install. What I want is something that I can give to a customer (either flash drive or cd) that they can put into their computer and all they have to do is double-click the program to run it. NO INSTALLATION. this Scan program must not only detect the mal ware, but also fix/delete it.
